2. 2. 2<br />SearchingTechniques<br /> Many problems in AI can be solved in theory by intelligently searching through many possible solutions. Reasoning can be reduced to performing a search. For example, logical proof can be viewed as searching for a path that leads from premises to conclusions, where each step is the application of an inference rule. Planning algorithms search through trees of goals and sub goals, attempting to find a path to a target goal, a process called means-end analysis. <br /> Basically we can divide searching techniques into many categories depending on their behavior.<br /> 1-Linear Search & Binary Search<br /> 2-Uniform Search & inform Search<br />
